C&C, or Command and Control is a facility located in Observation Dome 1 and serves as the central hub where all station operations, with the exception of security are run from. In times of attack, the observation window that the crew faces has a pair of blast doors which can be closed. Civilians are not allowed in C&C without express permission from the Commanding Officer. Officers who have a position are referred to by station numbers. Station 1, for example, tracks ships and is used at one point to continuously scan a Minbari warship to determine if they have hostile intentions.
Located directly opposite C&C across the station's central axis is a backup C&C facility in Observation Dome 2. In 2261 Dr. Elizabeth Trent and her team from IPX used this dome to co-ordinate the study of the Thirdspace artifact.
Located adjacent to the main docking bays, this is the first stop for all visitors to B5, and the last stop for those departing. All visitors must have the appropriate Identicard, visas and travel papers for approval before being allowed through customs. There is a passenger lounge on the station side of Immigration, so visitor can arrange to meet parties when they come through the gates, or say their goodbye before disembarking. The lounge itself features a number of public BabCom units for making or confirming hotel reservations, as well as exchange machines for converting Currencies and Credits.
Adjacent to the Docking bays and the customs areas are a number of secure impound lots. In 2262, Ambassador Mollari's shipment of Brivari was held in Impound 31, as due to a recent problem with infestation, a minimum 3 day impound on all food and drink, much to the Ambassador's disgust. While his Attaché Vir Cotto attempted to negotiate with Security Chief Zack Allan, Londo snuck a quick drink, only to be struck down by a severe heart-attack.
The customs areas feature scanners that can detect an concealed weapons, restricted substances such as Dust or anything suspicious on the passengers' person or luggage.

Later that year it again became a War Room when Sheridan and the Army of Light went on the offensive against Clark's forces.
The main docking bays make up the bulk of the internal volume of Blue Sector and run from the zero gravity main bay at the front of the station, down the elevator shafts towards the outer edge of the hull. Ships docking at B5 can choose between a variety of gravities from zero to one full Earth standard gravity, with the higher gravity bays closer to the hull and the lower gravity bays located closer to the station's central axis. B5 also features external docking facilities for the transfer of weapons and other banned goods. The docks on B5 are operated by the Docker's Guild, administrated by Neeoma Connally.

Located near the junction between Blue and Red sectors, the Cobra Bays get their name from the four structural elements of the forward sphere, each of which resembles a cobra with its hood extended. There are four cobra bays on the station, one on each of these structural elements. The station's complement of starfury and thunderbolt fighters dock in these bays. There are twenty-seven fighters prepared for launch at any time
The launching of fighters is facilitated by the station's artificial gravity, allowing the fighters to "drop" from the bays. Fighters are recovered through the main docking bay and then reloaded into the cobra bays.
